2]octane (DABCO)-catalyzed three-component domino reaction was developed for the synthesis of highly functionalized NH-pyrroles from arylglyoxal monohydrates, enamino esters, and cyclic 1,3-dicarbonyl compounds in 1,4-dioxane at room temperature for 0.5 hours. Various substituted NH-pyrroles were obtained in moderate to good yields.
开发了一种温和高效的 1,4-二氮杂双环 [2.2.2] 辛烷 (DABCO) 催化的三组分多米诺反应,用于从芳基乙二醛一水合物、烯氨基酯和环状 1,3-二羰基合成高度官能化的 NH-吡咯化合物在 1,4-二恶烷中室温放置 0.5 小时。以中等至良好的产率获得了各种取代的 NH-吡咯。
